Tornado, I have a very erratic way of making art, so I don't remember step-by-step. But this was created in Photoshop over many layers. CS5 added two powerful tools: bristle brush and mixer brush. Check them out, they're really great. I also experiment with various filters to "jiggle up" the strokes and add grit. The last step is always to selectively use the unsharp mask and gaussian blur filters. Thank you for asking!
